'.rne scheauisnfmea to in time mam Pfam ma making par. pf :ne me To all whom it muy concern: Y. Be it known thatI','GnoRen MILLER, of Providence, in the conntyotf. rProvidence and Stateof .Rhode Island, havelinvented anewand useful Improvement in Water-Illfheels';- and Ido hereby declare that the following is a full, clear, and 'exact deseription thereof, which will enable othersskilled in the art to make and use the same, reference being had to the accompanying drawing forming p'art of this specivThis invention relates toimprovements in waterwheels, and in the gearing for transmitting the power of the same.'

.It consists in mounting the large wooden or i-ro`n breast overshot or other whee1s,"commonly mounted on central shafts, on friction-rollers, and in transmitting the power through themedium of the said friction-wheels, geared together and arranged for gearing with suit-abletransmitting gear, the object being to simplify and cheapen the cost of the wheel and transmit-ting gear, as well as to reduce the friction 'of the bearings ofthe wheel.

A is the water-wheel, and

B, the rollers, onwhich it is supported, andv by4 which the power is to b.e transmitted. It is arranged `so that the faces'ofthe 'endrims ruu on the faces of the wheels B. 1

' The latter are arranged in pairs, vone for each end ofthe water-wheel, and connected to shafts C, which are geared Vtogether at one or both ends 4by an intermediate wheel, D, gearing into 'wheels E on the said shafts. y

This arrangement isapplicable vfor large, heavy wheels, which will bearon the wheels vB with such force as to prevent the wheel A from'slipping, or, in other words, the friction of thewheel-A-on the wheels `B must be greater than the powerof the water on' the wheel. This can be regulated'by the size of the wheels B. The-friction will be greater when the water is on the wheel.

The transmitting gearing may be connected in l any manner, and with any one of the wheels E or D, as may be preferred.

This arrangement admits of a cheaper construction of the water-wheel than when the central shaft and the necessary arms for support-ing it thereon are used, which have to'be very strong and expensive, and the wheel will last longer, for in this way the power of it being given off at both vends, and iat four different points, and these being where the wheel is supported,

-the strain is equally. divided on the wheel, so.that there are no twisting or cross-strains on it,- as when the gearing is connected to one point on the rim.

vThe strain is also less than when the power is transmitted through the shaft.

The transmitting shaft, gearing with wheels E, will have a speed as high as if geared into a Wheel on the shaft of the water-wheel, as ordinarily arranged, as

large as the rim of the water-wheel. y Of course the wheelgmonnted in this way will have less friction than whenI mounted in the o ld way. All theseadvantages are secured at less cost in firstconstruction t-han the cost of the present arrange nient, equal capacities being-considered.`

Having thus described my invention,

-I claim as new and desire to secure b'y Letters Patent- A water-wheel, mounted for its supportand also for transmitting its power on rollers B,the axles of which are vconnected together by gearing, and arranged for gearing with transmitting mechanism, all` substantially as specified.v

GEORGE MILLER.
